Pivotal announces new serverless framework

Pivotal has always been about making open source tools for enterprise developers, but surprisingly up until now the arsenal has lacked a serverless component. That changed today with the alpha launch of Pivotal Function Service.

Pivotal Function Service is a Kubernetes-based, multi-cloud function service. It’s part of the broader Pivotal vision of offering you a single platform for all your workloads on any cloud,” the company wrote in a blog post announcing the new service.

What’s interesting about Pivotal’s flavor of serverless besides the fact that it’s open source, is that it has been designed to work both on-prem and in the cloud in a cloud native fashion, hence the Kubernetes-based aspect of it. This is unusual to say the least.

The idea up until now has been that the large-scale cloud providers like Amazon, Google and Microsoft could dial up whatever infrastructure your functions require, then dial them down when you’re finished without you ever having to think about the underlying infrastructure. The cloud provider deals with whatever compute, storage and memory you need to run the function and no more.

Pivotal wants to take that same idea and make it available in the cloud across any cloud service. It also wants to make it available on-prem, which may seem curious at first, but Pivotal’s Onsi Fakhouri says customers want that same abilities both on-prem and in the cloud. “One of the key values that you often hear about serverless is that it will run down to zero and there is less utilization, but at the same time there are customers who want to explore and embrace the serverless programming paradigm on-prem,” Fakhouri said. Of course, then it is up to IT to ensure that there are sufficient services to meet the demands of the serverless programs.

The new package includes several key components for developers including an environment for building, deploying and managing your functions, a native eventing ability that provides a way to build rich event triggers to call whatever functionality you require, and the ability to do this within a Kubernetes-based environment. This is particularly important as companies embrace a hybrid use case to manage the events across on-prem and cloud in a seamless way.

One of the advantages of Pivotal’s approach is that Pivotal can work on any cloud as an open product. This in contrast to the cloud providers like Amazon, Google and Microsoft who provide similar services that run exclusively on their clouds. Pivotal is not the first to build an open source Function as a Service, but they are attempting to package it in a way that makes it easier to use.

Serverless doesn’t actually mean there are no underlying servers. Instead, it means that developers don’t have to point to any servers because the cloud provider takes care of whatever infrastructure is required. In an on-prem scenario, IT has to make those resources available.

The Cloud Native Computing Foundation adds etcd to its open source stable

The Cloud Native Computing Foundation (CNCF), the open source home of projects like Kubernetes and Vitess, today announced that its technical committee has voted to bring a new project on board. That project is etcd, the distributed key-value store that was first developed by CoreOS (now owned by Red Hat, which in turn will soon be owned by IBM). Red Hat has now contributed this project to the CNCF. Etcd, which is written in Go, is already a major component of many Kubernetes deployments, where it functions as a source of truth for coordinating clusters and managing the state of the system. Other open source projects that use etcd include Cloud Foundry and companies that use it in production include Alibaba, ING, Pinterest, Uber, The New York Times and Nordstrom. “Kubernetes and many other projects like Cloud Foundry depend on etcd for reliable data storage. We’re excited to have etcd join CNCF as an incubation project and look forward to cultivating its community by improving its technical documentation, governance and more,” said Chris Aniszczyk, COO of CNCF, in today’s announcement. “Etcd is a fantastic addition to our community of projects.” Today, etcd has well over 450 contributors and nine maintainers from eight different companies. The fact that it ended up at the CNCF is only logical, given that the foundation is also the host of Kubernetes. With this, the CNCF now plays host to 17 different projects that fall under its ‘incubated technologies’ umbrella. In addition to etcd, these include OpenTracing, Fluentd, Linkerd, gRPC, CoreDNS, containerd, rkt, CNI, Jaeger, Notary, TUF, Vitess, NATS Helm, Rook and Harbor. Kubernetes, Prometheus and Envoy have already graduated from this incubation stage. That’s a lot of projects for one foundation to manage, but the CNCF community is also extraordinarily large. This week alone, about 8,000 developers are converging on Seattle for KubeCon/CloudNativeCon, the organization’s biggest event yet, to talk all things containers. It surely helps that the CNCF has managed to bring competitors like AWS, Microsoft, Google, IBM and Oracle under a single roof to collaboratively work on building these new technologies. There is a risk of losing focus here, though, something that happened to the OpenStack project when it went through a similar growth and hype phase. It’ll be interesting to see how the CNCF will manage this as it brings on more projects (with Istio, the increasingly popular service mesh, being a likely candidate for coming over to the CNCF as well).
